Be it known that we, WiLLiAM Il. Me- .\nni.i; and ltoiir'irr l. Mtultniiuz, citizens of the lfiiited States, residing at Camden, in the county of Camden and State of New Jersey, have invented eertain new and useful liiiproveiiients in heet and lnvelop Feeders for 'l"vpe-'\\'riters, of which the following dest-i-iption, in connection with the aecompan ving drawings. is a specification.

This invention is. intended as an improve` nient on the class of paper feeding niet-haj nisiii Ashown in our lfnited States Patent 'Number 985,428. dated February 25th, 1911.

wherein. as deserihed. a frame or plate earr \ing a pile of sheets in an approximately horizontal position, is. eonneeted to and travels with the carriage of a typewriter, the other end of said fraine lieing supported by nieans independent of the typewriter carriage. and from which the sheets are con- -set'utively propelled to the typewriter h v rotary frietional members in contact with the topmost sheet. 'Uni' ohjetts in this iniprovenient being, tirst, to provide an approxiinatel)- horizontal paper carrying frame with a discharging end shaped to guide the sheets downwardli to sueh typewriters as are hy the pet'uliai' eon-truetion of their paper receiving ineehanisui untitled to receive sheets in a horizontal position: set'ond, to provide means for forwarding and preventing the sheets from laterally shifting while passing around .said hend; third, to provide means for separating all l other sheets from the .sheet ,immediately engaged h5' the feeding nieehanisni and detaining tht-iii until each is consecutively engaged by the feeding iiieehanisni; fourth, to provide z means for supl'ilenienting the separating and detainin;r niet-hanisni b v preventing the entire pile of sheets from advanting to the frame at onetime; fifth, to provide more f -suitable means for supporting the outer end of said paper carrying frame; sixth. to provide means in conjunction with said supporting means h v which the paper Carrying frame niav be permitted to travel longitudinally to aecoinniodate the backward and forward horizontal shift of soine typewriter.: i when shifting to capital letters or numerals and vit'e versa; seventh, to provide a convenient and instantaneous means for conneeting the paper carrying frame to the cari ringe of the typewriter; eighth,

to provide an improved torni of paper guide for the sheets in said frame: ninth, to provide anxiliary means for advaiieiingr the sheets after leaving the separator.

l`With-these and other ohjeet'sl in view,.as will more fully hereinafter appear, the invention eonsists in eertain novel features of ronstruetion and arrangement of parts hereinafter fully dest'rihed. \liowii in the aecompanving drawings. andparticularly pointed out in the appended elainis. it being understood that various eliaziges in the form, pr0- portions. .sr/.e and minor details of the structure may lie made without departing from tlieprineiple or saeritieing an)- of the :1dvantages of the invention.
